Assembly
Note: numbers in parentheses (#) refer to the
exploded view and parts list.
1. Remove the splash guard from the backside
of the lathe.
2. Remove the taper attachment from the box.
3. Remove the dust cover (29) held in place
with six screws (5).
4. Loosen and remove gib screws (16 & 24).
Do not adjust or remove gib screw (24A);
this will aid assembly when putting the taper
attachment together.
5. Remove the longitudinal slide assembly (6 &
11) from the slide base.
6. Thoroughly clean all parts of the taper
attachment with cleaning solvent.
7. Remove two nuts (A, Figure 1) and the
bearing cap (B, Figure 1) from the end of the
cross slide screw (C, Figure 1)
8. Remove the thrust bearing assembly from
the cross feed screw.
9. Remove two hex socket cap screws (D,
Figure 1) and the block (E, Figure 1).
10. Attach the main body (A, Figure 2) to the
carriage with two M8 x 30 hex socket cap
screws, and two M8 flat washers (B, Figure
2). Tighten the hex cap screws to hold the
main body in place but loose enough to
allow adjustment with a dead blow hammer,
or rubber mallet.
11. Place the cross slide block (A, Figure 3)
onto the taper slide rest (22).
12. Position the main body so that the hole in
the cross slide block (B, Figure 3) lines up
with the cross slide screw (C, Figure 3).
13. Push the cross slide block to engage the
cross slide screw through the hole in the
slide. It is important to get the slide to pass
over the cross slide screw smoothly. Use a
rubber mallet, or a dead blow hammer to
position the main body so that the slide
passes smoothly over the cross slide screw
without lifting it.

14. Make sure the inner bearing assembly is in
place before re-assembly, no spacer. The
smaller, inner diameter bearing goes on first.
15. Place the longitudinal slide (A, Figure 4) into
the main body.
16. Using a dial indicator with a magnetic base
(B, Figure 4) attached to the lathe bed, level
the longitudinal slide to the bed. The slide
assembly is level when it is less than .005”
from end to end. Keep the cross slide block
centered on the lead screw. Use a rubber
mallet, or a dead blow hammer to position
the main body so that the cross slide block
passes smoothly over the lead screw and
that the longitudinal slide is level.
Note: repeat steps 13 & 16 until the longitudinal
slide is level and the cross slide block passes
smoothly over the cross slide screw.
17. Tighten two M10 x 30 hex socket cap
screws that hold the main body in place.
18. Re-check the longitudinal slide for level.
19. Clean and lightly oil all gib surfaces that
were previously removed.
20. Replace the taper slide, gibs and gib
screws.
21. Check to make sure the slide moves easily
and without excessive play.
22. Replace the outer bearing assembly (A,
Figure 5). The smaller inner diameter
bearing goes on first.
23. Install two hex nuts (B, Figure 5). Tighten
the inner nut first to snug up the bearing
assembly. Turn the cross slide handle and
check for smooth rotation. Tighten the jam
nut to hold the adjustment.
Note: It is not necessary, but a good idea to drill
and pin the taper in place through the slide
bracket (3N).
24. Replace the dust cover.
25. Thread the lock down linkage (A, Figure 6)
into the end of the slide assembly (B, Figure
6).
26. Place the clamp (C, Figure 6) onto the lathe
bed and tighten two hex socket cap screws
(D, Figure 6).
27. Line up the hole in clamp with the lock down
linkage (E, Figure 6) and insert. Tighten the
hex socket cap screw (F, Figure 6).

28. Using a dial indicator mounted to the
carriage indicate along the tool post, while
moving the carriage, (Figure 7). You are
checking to see that the taper slide is
parallel to the movement of the carriage.
Note: You will need to loosen hex socket cap
screws (12 & 13). This will allow you to turn the
adjusting screw (18).
29. When the taper slide is parallel make sure
the screws (12 & 13) are tight, and mark the
zero point with a chisel.
• These taper attachments are designed and
intended for use by properly trained and
experienced personnel only. If you are not
familiar with the proper and safe operation of
a taper attachment, do not use until proper
training and knowledge have been obtained.
• Tighten the clamp bracket (59N) only when
using the taper attachment. You may want
to remove the clamp bracket when not using
the taper attachment.
